Flush Mac Addresses After A Topology Change; Mstp Sample Configurations - Dell Force10 MXL Blade Configuration Manual

To verify that EdgePort is enabled on a port, use the

FTOS Behavior: Regarding
1 If the interface to be shutdown is a port channel, all the member ports are disabled in the hardware.
2 When a physical port is added to a port channel already in error disable state, the new member port is also
3 When a physical port is removed from a port channel in error disable state, the error disabled state is
4 You can clear the error disabled state with any of the following methods:

Flush MAC Addresses after a Topology Change

FTOS has an optimized MAC address flush mechanism for RSTP, MSTP, and PVST+ that flushes
addresses only when necessary, which allows for faster convergence during topology changes. However, to
activate the flushing mechanism defined by 802.1Q-2003, use the
MAC addresses after every topology change notification. To view the enable status of this feature, use the
